Are your online stores safe from credit card stealers?
Given the rise in online payment, threat actors have become more sophisticated in attacking online stores to steal credit card information from the customers. The recent technique that the hackers used to penetrate the online shops is called Web Skimmer that uses CSS codes. Web skimming is a type of Internet fraud that targets to compromise the payment page on a website to filch payment information. While CSS file is used to design the content on the webpage’s font, size, colour, line spacing borders, indentation, and location of HTML elements.
Malicious scripts on CSS codes
The threat actors used the CSS file to hide their stealer script in the codes and blends within the payment website page. The malicious script can avoid being detected by the automatic security scanners and manual security code audits. Security researchers have noticed this credit card skimmer on three online stores. This attack is similarly known as the Magecart script, which is created by a group of malicious hackers that targets shopping cart systems. Magecart was labelled as one of the most dangerous people on the Internet in 2018 for compromising websites and planting card skimmers in several online stores.
As we go forward digitally, proper planning and execution of security precautions should be a necessity. The rise of e-commerce is growing fast, and online payments have their drawbacks. Placing robust security systems such as authentication steps, anti-malware, anti-phishing tools, compromised credit card recovery, end to end web security protection, and fraud detection should be considered to prevent attackers from compromising the systems.
